WlCK-TUBE FOR OIL-STOVES.

SPECIFICATION forming part of Letters Patent N 0. 406,027, dated July 2, 1889. Application filed November 30, 1888. Serial No. 292,246. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM H. CLEMEs, a citizen of the United States, and a resident of Cleveland, county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in \Vick-Tubes for Oil-Stoves, of-which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.

The object of my invention is the produc tion of a wick-tube so constructed as to cause the wick, when raised by the wick-raising shaft, to HTOVG unvaryingly upward in a line at right angles to the upper extremity or lip of the wick-tube-that is, to move vertically upward without canting to the right or the left.

Heretofore wick-tubes have been made either plane sided-that is to say, smooth sidedor have had corrugations extending to the upper extremity of the wick-tube. If the wick-tube is made plane sided or smooth faced on its inner side where the wick engages with it, it has been found by experience that as the e11- gaging-points of the wick-raising shaft force the wick upward the latter frequently has a tendencyto move toward one end or the other of the wick-tube, instead of moving upward in a vertical plane. This may be due to one or more of several causesviz., one of the wick-engaging projections 011 the shaft may not move the wick exactly to the same degree upward as another projection, owing to failure of catching with the wick, due to unevenness in the warp and woof of the latter. Again, in the usual form of wick-raising shafts the engaging-points, not being integral with the shaft, sometimes become loose, and said loosened portions fail to raise the wick as rapidly as the other projections, and the wick cants more or less as it raises, thus crowding it to one side. The result is that an airspace is left between the end of the wicktube and the wick, which causes the light to flicker and burn unevenly. So, too, when the wick-tube is corrugated all the way up, airspaces are formed intermediate of the side of the tube and the wick, which interfere with the proper and economical burning of the light, as has been stated.

Referring to the drawings, Iiigurc l. is a transverse section through the wick-tube, showing the wick in position, a portion of the reservoir also being shown in section. Fig. 2 is a longitudinal horizontal section through the wick-tube. Fig. 3 is a central vertical section through the wick-tube.

A is the top of an oil-stove provided with the usual wick-opening, and the flange asurrounding said opening. \Vick-tube l is formed in two sections 7.) I), each said section having formed integral with it at its lower edge the double angular formation a, that constitutes the burner-plate, and [its over the flange a, to which it is cemented or otherwise suitably secured. hen the two are formed separate from each other and are joined together, there has always been more or less weakness in the joint, with a consequent liability of the parts separating; but by forming them integral with each other the joint is done away with and the line of juncture between the two is as strong as either portion. Each wick-tube section has a planefaced lower portion 1- and a plane-faced upper portion 0, and is further provided with a series of vertical corruga tions (1, intermediate of said plane-faced lower and upper portions, said corrugations extending from a point about midway between the shaft and the burner-plate to a point a little more than half-Way from the shaft to the upper extremity of the wick-tube. The two sections of the tube diverge downwardly from each other, thus affording sufficient space between the sections to journal the shaft F centrally between them. By this means I am enabled. to pass the wickf to either side of the shaft, as desired, and may thus make either a right or left handed burner. The depressions of the corrugations are placed exacil y opposite the projections or engaging-points 5 of the wick-raising shaft, and thereby the latter is rotated the wick is crowded into said depressions and guided vertically upward, preventing all canting to one side or the other, and insuring a direct vertical movement of the wick. I now preferably make the proj ections and recesses of the corrugations about five thirty-seconds of an inch in width and about one thirty-second of an inch in depth.

Certain features of invention shown in this applicationnamely, the improved form of wick-raising shaft-do not constitute a part of. this application. Inasmuch as said features of invention form the subject-matter of another application of mine for United States Letters Patent now pending, as witness application, Serial No. 290,853, filed November 14, 1888, and hence all claims upon said feature of invention are rested in said other application.

The foregoing description and accompanying drawings set forth in detail mechanism in embodiment of my invention. Change maybe made therein, provided the principles of con struction respectively recited in the following claims are employed.

I therefore particularly point out and distinctly claim as my invention 1. In an oil-stove, the combination, with top A, provided with the upwardly extending flange a, of the wick-tube B, formed in sections, each said section having integral with it at its lower edge the angular burner-plate a, said plate having an outwardly-extending portion formed angularly to the wick-tube, and a downwardly-extending lower extremity the wick-raising shaft F, located between the opposite longitudinal walls of the wick-tube and in the same transverse plane with said corrugations, said'shaft provided with a series of wick-engagin g projections, respectively located opposite corresponding depressions of said corrugations, substantially as set forth.

In testimony that I claim the foregoing to be my invention I have hereunto set my hand this 27th day of November, A. D. 1888.

WILLIAM H. CLEMES.
